The extraction of Zn(II) ions from phosphating rinsing waters in automotive assembly process was investigated though a hollow fiber supported liquid membrane (HFSLM) by using di(2-ethyhylhexyl) phosphoric acid (D2EHPA)as a highly selective carrier for the transfer of zinc ions which diluted in kerosene and sulfuric acid solution have been used as the stripping solution. The various chemical parameters, such as the pH of the initial feed solution, the concentration of carrier, the concentration of stripping solution, the flow rate of feed and stripping solution were investigated. The optimum condition have been determined. The extraction of Zn(II) from feed phase was achieved at 91% by 8%(v/v) or 0.25 molar of D2EHPA. Mass transfer modeling in the systemwas developed to predict the extent of Zn(II) extraction at different time. Extraction equilibrium constant (Kex), distribution ratio (D), permeability (P) and mass transfer were determined. The aqueous-phase mass-transfer coefficient (Ki) and organic-phase mass-transfer coefficient (Km) were calculated.

Abstract This work presents the elimination of arsenic ions from synthetic produced water via hollow fiber supported liquid membrane (HFSLM). The effects of extractants, pH of feed solution, strippant solutions, and flow rates of feed and strippant solutions are duly investigated. Results demonstrate that arsenic ions in synthetic wastewater could be treated to comply with the standard of wastewater discharged (< 0.25 mg/L) via HFSLM. Percentages of extraction and stripping proved to be 100% and 98%, respectively. Thus, in a single-step operation, arsenic ions are extracted and stripped, using 0.5 M Aliquat 336 as the extractant, at pH of feed solution of 12, with a mixture of thiourea and hydrochloric acid (0.5 M each) as the synergistic strippant solution, and flow rates of both feed and strippant solutions of 100 mL/min. A mathematical model has also been developed to predict the final concentration of arsenic ions in feed and strippant solutions. The results predicted by the mathematical model fit in well with the experimental results.
